LOCKING CLIP.

Original application filed February 3, 1922, Serial No. 533,860. Divided and this application filed March 10, 1924. Serial No. 698,189.

To all whom it may concern:

Be it known that I, GEORGE R. LAWRENCE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain newand useful Improvements in Looking Clips, of which the following is a specification.

The present invention relates to locking clips, and this particular application is a division of my co-pending application, Se-

rial Number 533,860, filed February 3, 1922, for Letters Patent for improvements in ovens, upon which application Letters Patent Number 1,486,528, was issued to me on the 11th day of March, 1924, and is directed to a type of clips shown and described in my aforesaid co-pending application, for use in locking or holding together adjacent or abutting structural units, entering into the makeup of the oven.

The present invention, while primarily intended for use in ovens of the type disclosed in my said co-pending application in looking or securely holding together or in place at their adjacent or meeting surfaces certain units of the oven, and so that hermetically sealed joints will be provided, to the end, that the passage of dust and the like into the oven will be prevented, yet, the invention' is applicable for use in numerous other kinds of structures, and I wish it understood that I do not desire to be limited in its application, but may employ it wherever it may be found desirable or applicable without a departure from the spirit of the invention as expressed in the appended claims forming a part hereof.

One of the objects of the invention is the provision of a very simple, inexpensive,

40 strong and durable clip for locking parts together in relative positions to one another.

Another object is the provision of a looking clip of such construction and characteristics that it can be readily attached to or detached from the locked members, for reuse, if desired.

It is another and important object of the invention to provide a locking clip having means co-operating with engaging parts of the members to be locked or held together, orinrelative positions with respect to one another, whereby air tight or hermetically sealed joints will be afforded between the clip and said engaging parts.

- Other objects and advantages of the invention will be disclosed in the following descrlption and explanation.

In the accompanying drawing, which illustrates embodiments of the invention, fragments of a pair of parts to be connected together by the clip are shown, which fragmental parts may be equivalent to the clipengaging parts of a pair of the adjoining units of the oven shown in my said co-pending application; but as before stated, as the clips embodying the invention are of general utility and not limited in their application to any particular structure, I have shown in the drawing only fragments of apair of parts to be united or locked by the clips so as to clearly illustrate the principles of the invention and the application of the in operative position on the clip-engaging members of the parts to be locked or held together thereby.

Fig. 3 is a view similar to Fig. 2 but illustrating a modification in the construction of the clip. 7 1

Fig. 4 is an end view in elevation showing still another modification in the form of the clip.

Like numerals of reference refer to corresponding parts throughout the different views of the drawing.

Referring now more particularly to Figs. 1 and 2, of the drawings, the reference numeral 8 designates generally or as a whole one of the clips which is made of sheet metal and may be made of any desired length and other dimensions. The clip of the form now .underconsideration is provided about midway between the extremities of its sides with an outwardly extended loop 9 which is disposed longitudinally with respect to the clip and said loop is provided in each of its sides with one or more pairs of registering openings 10 for the reception of a screw-bolt or bolts ll to be used for the purpose presently to be explained.

7 near the juncture of the sides of the clip As shown, the sides of the clip diverge and each has at its side edge an inturned llange 12 to engage the free edge orend-of ahhpengaging extension 13 on each of the parts 14 to be united and held or locked together "by the clip.

The'm'enibers 14 constituting .the p arts to be connected together by the clip are shown. as being in oontactrW D 6 e ihfi at "their adjaeent surfaces, aandjwhileltheywill generally be so eiaeeayjye ni y may be spaced? at vtheir adjac en t snrfaces and held in eh spaced relation by any eeme means} not shown. "Theclip-engaging ex- 4 .connected: togeth'e;

tensions or members 13am of conrselpcated externally of the parts 14, v and 3 while they areshown as being connected tosaid parts at the adjacent surfaces thereof, yetit is manifest that said olipengaging a extenslons may be connected to .tl1eirQrespectiye parts 14 near the adjacent sur-faees of said, parts,

yet extended therefrom in such a way as to members '13 i and thereby forming air -tight closureslbetween the clip and the 'Inembers 13"or hermetically sealing the same v at said points. Each ofthe flangesr l2 is inwardly extended or cross-sectionally .disposedfin spaced relation to" each of the outwardly deflected portions 15"as is clearly shown; and by this arrangement it is manifest that e fefle ses' i l he e b rs 13 'n p ed between thefianges 12 and parts will rest against theinner surfaces of the flanges 12 andtliereby provide an additional air-tight closure.

It will be observed by reference to Figs.

1 and 21s ofthe drawing, that. theopenings 1O i'n'the side walls of the loop 9 are located with the loop 95 which loop normally, see

' Fig; 1, inwardly flared. hen the clip is in its normal condition asshown in'Fig. 1,

the free edges of the. flanges 12 willibe closer 7 together than when thejolip is applied to theZclip-engaging members 13' as illustrated in Fig. 2,' and by reason of this further divergence. of the sides of the cli'p,, thebead like formationltl formed by the outwardly deflected portions 15v will be rendered more prominent as will be understood refer ence to. Figs. '1 and 2 ef the drawing, thus positively presenting to theouten surface of the olip engaging members 13a sealing rib or bearlng.

It will be understood that the clips are made of resilient material, and after springving the sides thereof sufiiciently from each other to permit the flanges 12 to engage the free ed-ges of the members l3 -and releasing pressure fro ngthe clip, the resultant re-. action of the yielding clip will cause the flanges 12 and portionsn 1 -5. and l6 =tozocoupy out h ip tion tr la ive to he-.;:me1nbers;

From the foregoing and by reference to the drawing, it will be readily understood and clearly seen that by my improvements I have provided a clip which can be readily attached to the parts to, *be held together thereby or if desired, can be easily detached therefrom. It will also be understood that the space between the sides of the clip and the clip-engaging members 13 of the parts 14 to be held together can be supplied with a filling of plastic material such as plaster of Paris or any other suitable substance which is frangible after becoming set or hardened, thus, the material can be readily crushed when it is desired to detach the clip from its support.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A locking clip consisting of a piece of resilient material cross-sectionally deflected from the plane of its side edges and having at one of its side edges an inturned flange spaced from said edge, that side edge of the clip on which said flange is provided being upwardly deflected from the said plane of the side edges of the clip.

2. A locking clip consisting of a piece of resilient material cross-seetionally deflected from the plane of its side edges and having at one of its side edges an inturned flange spaced from said edge and at its other side edge means to engage a part on one of the parts to be held together by the clip, that side edge of the clip on which said flange is provided being upwardly deflected from the said plane of the side edges of the clip.

3. A locking clip consisting of a strip of resilient material cross-sectionally deflected from the plane of its side edges and having at each of its side edges inturned flanges spaced from said edges, the side edges of said strip being outwardly deflected from the planes of said cross-sectionally deflected portion forming bearings.

4. A locking clip consisting of a piece of resilient material cross-sectionally deflected from the plane of its side edges and provided between said edges with an outwardly extended loop, said loop having a pair of registering openings in its side walls, said piece having at its side edges inturned flanges spaced from said edges, the side edges of said piece being outwardly deflected from the planes of said cross-sectionally deflected portion forming bearings, a

screw bolt having a head on one of its ends and extended through openings in said loop gnfl a nut engaging the other end ofsaid GEORGE R. LAWRENCE.
